What should engineers review before using US3D?

Check the 1.0 V maximum forward voltage at 3 A, 50 ns maximum reverse recovery time, 90 A single-half-sine surge rating, reverse-voltage margin, and PCB thermal design. The 3 A rating is specified for single-phase half-wave operation; capacitive-load current requires a 20% derating.

What is the pinout of US3D?

Use the US3D datasheet for the official pinout diagram and pin names. In PartGenie, ask Datasheet AI about US3D pinout to locate pins, power rails, and interface signals before layout.

AI summary

US3D is a 200 V, 3 A ultrafast SMB rectifier diode with 50 ns maximum reverse recovery time.

Best for

Fast rectification in compact surface-mount power circuits
200 V reverse-voltage applications within the specified current and thermal limits

Avoid if

Required reverse voltage exceeds 200 V
The design requires a specified lower forward drop than 1.0 V maximum at 3 A
Lifecycle-controlled sourcing is required without further verification

Check before use

Validate junction temperature with the actual PCB copper area
Confirm cathode orientation: pin 1 is cathode and pin 2 is anode
Apply the datasheet capacitive-load derating where applicable
